I just finished a product design. In the design, the measured data needs to be uploaded to the PC via USB. I used the simplest method: "Serial Port convert to USB" and one IC can do it. The product ha...
Can anyone help me calculate the resistor values of this circuit diagram? http://s3.photo.qq.com/567172606/94699521 (Sorry, I don't know how to post pictures.) The transistor is 9014, the thyristor is...
Power supply is often the most easily overlooked link in the circuit design process. In fact, as an excellent design, power supply design should be very important, which greatly affects the performanc...
Has anyone used Bosch's PM sensor?
It's Bosch's carbon smoke sensor. There is no communication protocol when I bought it. I'm begging (helpless) for the communication protocol......
Assume that data is read from 8-bit AD (if it is a higher-bit AD, the data type can be defined as int), the subroutine is get_ad();
